Abstract
In this paper, we prove that solutions of the anisotropic Allen–Cahn equation in doubleobstacle form where A is a strictly convex function, homogeneous of degree two, converge to an anisotropic mean-curvature flow when this equation admits a smooth solution in ℝ n . Here VN and R respectively denote the normal velocity and the second fundamental form of the interface, and More precisely, we show that the Hausdorff-distance between the zero-level set of φ and the interface of the above anisotropic mean-curvature flow is of order O(ε 2).
